SASH-HOLDER.

SPECIFICATION forming part of Letters Patent No. 246,'704, datedSeptember 6, 1881.

Application filed July 8, 1881. (Moden To all 'whom it may concern Be itknown that I, ALBERT AYERS, of Rahway, in the county of Union and Stateof New Jersey, have invented an Improved YVindow-Stop, of which thefollowing is a specification.

This invention relates to that class of devices which are designed tohold window-sashes at any desired elevation, and to prevent their ratotling, and is especially designed for car and carriage windows.

The invention consists of a rnbber tube closed at one end, provided witha head having a polygonal face or edge and a projecting 1 central boss,and containing a loosely-fitting rigid pin, which tube and pinconstitute the stop, several of which are designed to be set in suitablesockets in the edges of the sash, so that opposite faces will bearagainst the sides zo of the sash-grooves in the window-frame and thebosses against the bottoms of the grooves.

Figure l is a partly-sectional front elevation of a carriage-window sashon line y y, Fig. 2,

. showing my improved device attached. Fig. 2 is a section-al sideelevation of the same on line xx, Fig. 1. Fig. 3 is an enlargedseetional elevation of a stop in position on line zz, Fig.

4. Fig. 4 is a plan. of a stop. Fig. 5 is a sectional elevation ot' amodification of the stop 0 on line e v, Fig. 6. Fig. 6 is across-section of the modified stop on line w w, Fig. 5.

Similar letters of reference indicate corre sponding parts.

In the drawings, A represents a windowframe provided with sash-groovesA', and B represents a sash provided with sockets a for holding thestops O. A stop, O, consists of a rubber tube, C', closed at one end,having an annular polygonal-faced head, b, and a central 0 projectinghemispherical boss, c. Said stop C is set in a socket, a, in the sash.The boss c and the outer portion of the head b are designed to projectfrom the window-sash, as shown in the drawings, so that opposite facesof the head I) (which head l is wider than the edge ot' the sash B)shall extend beyond the faces of the side rails of sash B, as shown inFig. 2. By said head b bearing against one or the other or both of thesides of the grooves A' in the window-frame as said sash B is moved upor down, rattlin g is prevented, and at the same time the hosses c,always bearin g against the bottons of the opposite grooves A', holdsaid sash B in any desired position. The rigid pin D, which is a part ofthe stop G, is inserted through the open end of the tuheC' and reaehesto the top of the annular portion of the head b. Said pin D is enlargedat its lower end where the tube G' fits tightly about it, and is reducedfor the remainder of its length, as 6o shown in Fig. 3, so that the saidtube G' nay be longitudinally comprcssed and retain enough elasticity toaceonnodate itself to the width of the window-franie A, and at the sametime sufficient rigidity to hold the sash B in position, the said pin Dbeing long enough to prevent the boss c froni being pressed inwardbeyond the face of the window-sash.

E represents a thunb-piece on the sash B,

by which the latter may be moved up and down.

In Figs. 5 and (i is shown a modification, H', of the stop, in which Frepresents a tube fully open at one end and partially closed at theopposite end. Up through this tube F, from the smaller to the larger endthereof, is passed a pin, G, the lower end of which is enlarged, asshown at f, to prevent its further entrance into the tube F, while onthe opposite end of said pin G, which projects through the tube F, isfixed a circular convex button, H, of rubber, whose shank g is free tomove up and down within a limited range in the said tube F. About thepin G is a spiral spring, I, one end of which bears against the buttonH, while the other end bears against the inside of the bottom of thetube F. This modified stop, when used, is designed to be setwithinadeeper and shouldered socket in the window-sash B, so that the pin Gmay be free to move in and ont; and the button H is designed to hearagainst the sides and faces of the grooves A'. These rubber stops O H'hold a sash firnly and do not rnb the paintor varnish from thewindowframe, and the parts of them in contact with the window-frame,being made of Vulcanized rubberor rubber compounded with soapstone orother suitable substance, are very durable and move Without stiekng.

Having thus described my invention, I claim as new and desre to secureby Letters Patent Iu &window-stop, the 'ubber tube C', having an annularpolygonal head, b, and projecting central boss, a, and the pin D,substantally as hereiu shown and described, whereby xo the stop is madeto hear on the sides and faces of the window-frames grooves, as setforth.
